To all whom it may concern:

Be it known that I, JAMES A. NOBLE, a citizen of the United States, residing at Hoosick Falls, in the county of Rensselaer and State of New York, have invented new and useful Improvements in Attachments for Beating-Engines and other Stuff-WVorkspecification. My invention relates to machines for pre paring and treating paper stock, such as breaking engines and mixing engines, and consists in providing such machines with the means hereinafter described for removing foreign material from the stock. 7

It is' customary in many paper mills to use stock containing strings in greater or less quantities but, in all the processes through which such stock passes in preparation for treatment in the paper machine, these strings are troublesome as they are liable to, and do wind about the moving parts and accumulate in hard masses which interfere with the operation of the machinery, often finally making it necessary to stop the engines and to cut out the strings by hand, which causes a large loss of time and labor. It is impracticable to" remove the strings from the stock when it is dry, as the labor would be far too great. Consequently, the stock must go into the stuffworking engines, strings and all.

In the accompanying drawings, I have illustrated my improvement as applied to a beating engine, although it is'equally adapted for use in other stuff-working machines, as mentioned above.

In said drawingszFigure 1 is a partial longitudinal vertical section through a beating engine vat supplied with my improvement. Fig. 2 is a plan view of the same. Fig. 3 is a vertical cross section of the vat on line 3-3 of Fig. 2, and Fig. 4 is a side elevation of the side of the vat equipped with my improvement.

1 represents the sides of the vat of a beating engine, 2 the midfeather and 3 the backfall.

4 is the beating-roll and 5 the cooperating bed-plate, all of said parts being of the usual construction.

My improvement consists in providing a rack 9 to act as a string catcher, the same 'ATrAenMENT non BEATING-ENGINES AND oTHnnsTUrr-wonmne rancnnvns.

beingfmounted in front of the beating-roll,

as shown. It consists of a shaft 6, journaled 'in'bearings 7, 8, mounted on the side of the vat and on the midfeather, respectively, on

which shaft 6 is mounted a plurality of fingers or teeth 10, 10, suitably spaced apart on said shaftbetween'the side of the vat and the midfeather. ,Theseteeth are preferably curved at their lower "ends, which extend close down to the floor of the vat.

On the outer end of said shaft 6 is mounted a gear-segment 11, with which meshes a pinion 12, fast on a short shaft 13, journaled in bearings 14, carried by a bracket 15, bolted to the side of the vat. Alongside said pinion the shaft 13 carries a ratchetwheel 16, and on its outer end is secured a hand-wheel 17, by which it and the shaft 6 can be turned to elevate the rack 10.

an arm 18, carrying a counterweight 19 at 1ts outer end, is secured to the shaft 6, or to the web of the gear-segment 11 near its hub, said arm projecting rearwardly from said shaft, so that the counterweight tends to turn the same to elevate the rack, in other words, to partially balance the weight of the rack teeth.

To hold the rack in any intermediate position to which it may be raised by the handwheel and gearing, I provide a pawl 20, pivoted on the bracket 15 and having a counterweight rear end 21, which holds its front end in engagement with the ratchet. The pawl is released, when it is desired to lower the rack, by the foot-treadle 22, to

' the rear end of which is pivotally connected a trip-rod 23, guided in the bracket 15 and engaging with its upper end under the counterweight arm of the pawl. A standard 25 serves to adjustably support a pillar 26, which takes into a socket 27 in the bracket 15. This string-catcher can be applied to vats of different sizes by lengthening or shortening its teeth and adjusting on the side of the vat and on the Inidfeather,

V the teeth of said rack being ofa length to reach close to-thebottom of the Vat, a gear on said shaft outside the Vat, a pinion in mesh with said gear, a hand-wheel and a ratchet-wheel on the shaft of said pinion, a

'pa'wl engaging said ratchet-wheel to hold the rack in elevated position, and means to 15 trip said pawl.

2. Means of the class described, comprising a shaft, a plurality of rack teeth secured thereon, a second shaft'iproirided with a hand-wheel and a ratchet-wheel, gearing like, a pawl mounted to normally engage said ratchet-Wheel, and ineans for disengaging said pawl when it is desired to turn said shafts to lower saidrack teeth into the Vat. In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses. I
